6-Way RadeonSI OpenGL vs. RADV Vulkan Comparison

Dota 2 at 1080p showed the RadeonSI performance generally leading over the unofficial RADV Vulkan driver. But with the RX 580 and R9 Fury the performance ended up being extremely close between the competing drivers.

With Mad Max in the Camp Hollow Point scene at 1080p, the RADV Vulkan performance was faster than OpenGL. The higher-end cards tended to be CPU bound at 1080p with low quality settings in this Feral Interactive game port.

With the stronghold scene, Vulkan remained faster but again was a CPU bound scenario.

The hope, glory, and dog is dead scene showed the RADV Vulkan performance still doing good with the higher-end AMD GPUs. The peak frame-rates though were higher with OpenGL over Vulkan.
